you should be able to handle 1000 visitiors/day with a modern smartphone :) if your vps are running on the same host i'd suggest to strip down your setup to 2 machines and apply more ram/cpus for each machine, maybe in a hot-standby-scenario with a switchable failover-ip. regards, mex Posted at Nginx Forum: http://forum.nginx.org/read.php?2,236068,236072#msg-236072
